Isolates from watermelon-growing areas were classified into 3 races like race 0, race 1 and race 2 which were 8 (17.4), 30 (65.2), and 8 (17.4%), respectively. Pathogenecity of race 0 isolates are weakest which only make Sugar Baby susceptible; isolates of race 1 are intermediately pathogenetic, they make Sugar Baby and Charleston susceptible Gray but Calhoun Gray resistant; isolates belonging to race 2 possess the strongest pathogenecity, which make 3 hosts susceptible. Isolates of race 0 mainly distribute over the central and southern Hebei province, whereas race 2 cover the middle and north of Hebei, isolates of race 1 exist in the whole watermelon-growing areas in Hebei province.
根据鉴别寄主对供试菌系的抗感反应，将46个西瓜枯萎病菌系划分为0号、1号和2号3个不同的生理小种，分别包括8，30和8个菌系，占供试菌系的17.4%、65.2%和17.4%；0号生理小种菌系致病性最弱，仅使品种Sugar Baby感病，以冀中和冀南居多；1号生理小种菌系致病力中等，使鉴别寄主Sugar Baby和Charleston Gray感病，而使Calhoun Gray抗病，分布在整个河北省西瓜种植区；2号生理小种的菌系致病力最强，使3个鉴别寄主均能感病，主要分布在冀中和冀北。

The new chimeric infectious DNA clone and its derived, a virulent chimeric virus are constructed from the nonpathogenic PCV1 in which the immunogenic ORF gene of the pathogenic PCV2 replaces a gene of the nonpathogenic PCV1, preferably in the same position.
所述新型嵌合的传染性DNA克隆及其衍生的有毒力的嵌合病毒是用非致病性PCV1构建的，其中，致病性PCV2的免疫原性ORF基因取代了非致病性PCV1的基因，优选是在相同的位置上取代。

The results revealed that there was nosignificant difference between the symptoms produced by the mutant and thewild type strain by directly injecting the bacteria into mature turnip leaves,however,the mutant was nonpathogenic by inoculations with leaf-clippingand-spraying methods.
应用不同的接种方法对胞外多糖突变体的致病性进行了分析，发现突变体通过注射接种仍能产生与野生型相同症状，但通过喷雾和剪叶接种却完全丧失了致病能力，说明甘蓝黑腐病菌产生的胞外多糖可能在致病过程的早期阶段起作用，但对症状的产生不是必须的。

However the three mentioned analysis methods has been so far assured only available to high pathogenic pathotype identification, which was probably associated with the high expression of gene related to high pathogenicity, on the other hand, pathogenicity differentiation of Cercospora zeae-maydis was probably controlled by some complex factors regulated by by polygenes.
相比较而言，只有强致病类型菌株利用三种方法进行鉴定有一定程度的相关性，这可能与强致病类型致病相关因子在蛋白质和DNA水平上的表达强度高有关，另一方面可能是有复合因子控制灰斑病菌的致病性分化，这恰好反映出该病菌的抗性遗传是由多基因控制的特点。

The results showed that 9 pathogen collections of Sporisorium reilianum were divided into 3 pathogenic types in which there were type A with high pathogenicity, type B with moderate pathogenicity and C with weak pathogenicity. Type A were originated in most important corn-grown areas including Changchun ,Jilin,Gongzuling and Changling where corn head smut usually occurs severely, type B were collected from Siping,Tonghua ,Songyuan,Yanbian, and type C were collected from Baicheng where corn head smut usually occurs very lightly.
致病类型A为强致病类型，来源于吉林、长春、公主岭和长岭，是玉米丝黑穗病发生最严重的地区；致病类型C为弱致病类型，分布于白城地区；致病类型B其致病性介于A、C类之间，主要分布于四平、通化、松原和延边地区。
